The DS2502P+ is a silicon serial number IC that is designed to provide a guaranteed 64-bit registration number that can be used to uniquely identify a device in an embedded or portable system. It uses a secure, factory pre-programmed, 16-bit version of the IEEE code embedded in a silicon die to provide a registration number that can be used to assure product authenticity. The DS2502P+ is available in both an 8-pin TSSOP package, and an 8-pin SOP package for applications that require a small footprint.

The DS2502P+ has wide range of applications. It can be used to uniquely identify gaming consoles, mobile phones, case storage media, toys, and many other consumer electronic products. It can also be used in automotive systems, laptops, and portable electronics. The privacy features of the DS2502P+ make it an ideal solution for near field communication (NFC) applications, such as contactless payments and door access.

The working principle of the DS2502P+ is based on the IC\'s embedded 64-bit one-wire ROM that can be accessed using a compatible 1-wire reader. The ROM memory areas contain manufacturer specified information, such as the serial number and production codes, as well as basic descriptive information about the IC. All communication between the reading device and the DS2502P+ is done via a single pin. This allows the device to be programmed and read from a remote location, making it well suited for applications that require remote activation and device authentication.

The DS2502P+ also includes a unique signature register and a unique 64-bit number that are used for authentication. The signature register is a read-only register, containing a 16-bit authentication code and a 48-bit serial number. The authentication code is used to verify that the device is genuine and can only be altered by the manufacturer. The serial number is used to uniquely identify each device, providing the manufacturer with a way to track the end-user\'s product. This ensures that the original product is authentic and not a counterfeit.

The DS2502P+ also provides a secure, factory programmed, 16-bit version of the IEEE code that is embedded in a silicon die. This provides the manufacturer with an added layer of security. In addition, the DS2502P+ offers a number of features such as write-once programming, password protection, and device lock-up, which all help to ensure the security and authenticity of the product.

To summarize, the DS2502P+ is a high-performance silicon serial number memory IC, offering a guaranteed 64-bit registration number for unique device identification in embedded and portable applications. It contains a pre-programmed 16-bit IEEE code embedded in a silicon die, as well as a unique serial number, signature register, and a number of features such as write-once programming, password protection, and device lock-up, which all contribute to the secure authentication of a device.
